“There is no CCTV on the stretch of road so there is no evidence to say why she suddenly turned left.”

Sinead’s Renault Clio was found on its roof but she was still inside held in place by her seatbelt.

Her husband Nathan Symes has been left devastated.

He said: “Sinead was a gorgeous, caring and trustworthy person, whilst also being a truly independent woman who just enjoyed having fun, and whose smile and laughter was infectious with anyone she came across.

“She was the most fantastic and dedicated mum to our beautiful daughter Orla Rose, for whom I am eternally grateful for and I vow that Orla Rose will grow up knowing her mummy.

“I am so proud and honoured that although Sinead and I were together for almost seven years, I was able to call her my wife for 106 days.”
